Hi according to the documentation, this hook’s signature accepts 3 arguments:
Filter Hook: user_meta_form_display (since 1.1.3rc2)
Applied to form html before browser output.
Function arguments: HTML (string), Form Name (string), Form Data (array)
I’m can only get HTML argument working, the other two are missing so I get this error:
Warning: Missing argument 2 for add_register_link() in...
BTW add_register_link() is the name of the function I use after calling the hook.
Number of accepted argument (4th argument) value might be missing while you called add_filter
Here is a quick example:
add_filter( 'user_meta_form_display', 'user_meta_form_displayFunction', 10, 3 );
function user_meta_form_displayFunction( $html, $fromName, $formData ){
//Your code here
return $html;
}
